Output amount is now a string

BigchainDB transactions may have multiple inputs and outputs, and each output has an amount, which is the integral number of the asset being transferred. In prior versions of BigchainDB, the amount was encoded as a number, which on the face of it is the obvious way to encode an integer. However, as usual the devil is in the details; JSON, the encoding of choice for BigchainDB transactions, encodes all numbers including integers as floating point. This isn't a problem for the majority of circumstances where numbers are small, however in some environments and for some use cases*, the number may lose precision.

In order to safeguard against this, amounts are now encoded as strings, and it is recommended to use a decimal math library (such as big.js) when dealing with large numbers in Javascript. Additionally, numbers are capped at 9e18 to stay comfortably within the boundary of a 64 bit signed integer.
